There are sports car owners and there are sports car drivers. The reality is to use something like a Ferrari, Lambo, R8, GT500, ZR1, etc to its full potential you need to spend some time in driving school and then play with it on a track. For a certain subset of people this is their main hobby and worth it. For others they buy it as a status symbol and promptly wreck it (The GT500 was dubbed the "stockbroker killer" due to its popularity with that crowd and the frequency of their wrecks).

For street driving, once you hit a certain performance point you're mostly just pissing your money away. I like my CTS-V for dealing with dickhole truckers that play passing games, as the minute a gap opens up I can hit the pedal and be through it, but really most of the time that engine is just cruising along under 2k RPM and sucking gas. My Grand Prix GXP with its 303 horse can do the exact same thing.

/of course the Prix steers like a biatch on the track, while the V doesn't//if I reach the point where the steering difference becomes noticeable on the highway I am engaged in both illegal and stupid activity

I'll add that I have driven a six figure sports car on a track- an Audi R8 V10.

The sheer experience is amazing. The capabilities of those cars is so far beyond what we normally think of as good that you can't fathom it without experiencing it. Going foot to the floor and having over 500HP explode behind you while snapping off shifts in less than a second is just something that you don't get short of anything else in the same class. It took all day for the stupid grin to leave my face.

The thing is, such vehicles aren't really a good idea for everyday driving. If you dropped me off at the nearest dealer of such vehicles with $200K in my pocket I'm not even sure that I'd buy one. But if I had millions upon millions of dollars and could buy the things by the dozen while building new garage space without a glance at the checkbook, sure. I could see owning several of those things. But they'd represent less an investment of my total value than my Jeep does now. It's just a completely different way of thinking... if you can do it, it must be nice.
